GRAIN-BINDING MACHINE:

SPECIFICATION forming part of Letters Patent No. 278,524, dated May 29,1883.

Application flled June 26, 1882. (No model.)

less belts or aprons carried by upright rolls are arranged to travelobliquely across the end of the binding-table or grain-board, for thepurpose of shifting the grain endwise during its passage toward or intothe binding mechanism, and thereby securing the central application ofthe band.

The improvement consists in a bracket de-' signed to sustain bothjournals of the roll by which the upper end of the adjuster-belt iscarried, and also the journals of one end of one or both of the rollscarrying the upper end of the conveyer-aprons, whereby said parts andthe connecting-gears are maintained in the proper relative positions.

Referring to the accompanying drawings, Figure 1 represents a top planview. of a machine of the well-known Esterly-Appleby type having myimprovement em bodied therein. Fig. 2 is a side elevation of one of myimproved brackets or standards and the parts connected therewith. Fig. 3is a vertical section on the line w x of Fig. 1.

Referring to the accompanying drawings,A represents the upper part ofwhat is commonly known in the art as an elevator-frame',or A- frame, ofthe ordinary harvester, containing the transverse rolls B,which sustainand drive the two canvas aprons, (J, by means of which the grain iselevated from the harvester-platform and delivered to the binding-tableor the harvester-frame, the above parts being of the ordinaryconstruction and arrangement,

tion.

In practical operations in the field it is found that the grain variesgreatly in length, in consequence of which it is necessary to shift thesame endwise as it descends to the binding mechanism, in order that thecentral application of the band thereto in all cases may be secured. Forthis purpose I employ,

as in other machines well known in the art, one or more endless apronsor belts mounted upon rolls perpendicular to the surface of thegrain-table and arranged to present the upright surface of the apronacross the end of the table in a path oblique to the path of the grain.In the present machine I have represented two of these belts, 0,arranged at opposite ends of the grain-table to act upon the heads andbutts 0f the grain, respectively.

As shown in Figs. 1, 2, and 3, each belt is carried at its two ends bymeans of rolls P Q,

which rolls have their journals mounted in a swinging frame, It. Thisframe revolves about the journals of the upper roll, P, as an axis, in

order that the lower end of the apron may be adjusted laterally and theinclination or obliquity of its face to the path of the grain be variedas the length of the grain may require. The journal of the upper roll,P, is provided at the lower end with a beve1-pinion,U,which receivesmotion from a corresponding gear,V, applied. to thejournal Tof that rollwhich carlies the upper end ofthe lower conveyer-apron, as representedin Figs. 2 and 3.

My invention has special reference to the manner of supporting the upperroll, P, and maintaining. the same in the proper relation to the journalT. To this endI provide a rigid standard or bracket, S, such as clearlyrepresented in Figs. 2 and 3, the same consisting of a base portionadapted to be bolted to the side of the elevator or harvester frame, andof an upright standard or portion rising there-' from above the surfaceof the grain-table. The upper end of the standard is provided with abearing to receive the upper journal of the roll -P,while the baseportion is provided with hearings to receive the lowerjournal of theroll P, and also the journal T of the lower elevator-roll. The baseportion is also pro-' vided, as shown, with openings to receivefastening-bolts.

It will be observed that the standard thus constructed will sustain theroll P in its proper position, and that it will at the same timemaintain the end of said roll and its pinion in the proper relation tothe gear of the elevatorroll by which the adjuster-roll is driven.

In practice it is found that by the employment of this construction thecertain and positive action of the parts is secured, and that thedifficulties hitherto experienced on account of for the journals of oneend of the elevatorthe gears U V being thrown out of position rolls. areentirely avoided.

The stationary bracket S,constructed, may be made to serve as a bearing for'the as described, toafford a bearing for one end 15 5 journals of one or both of the upperelevatorof one or both of the elevator-rolls, and also it rolls, asrequired. bearing for the lower journal of the upright Having thusdescribed my invention, what I adj uster-roll. claim is- GEORGE ESTERLY.
